Hi Kzrysztof,
Thanks for your report.
Because I use 13 stable and cannot test the current,
your report is very useful to me.
I'm using ThinkPad X1 nano which has a AX201.
I have some questions.
Do we need the 'if_iwlwifi_load="YES"' line
in addition to the 'kld_list=if_iwlfiwi' line?
I don't think so, but I may be wrong.
Do you use "wifimgr" which is a GUI tool to select AP.
When I use "if_iwlfiwi.ko", wave strength displayed
in wifimgr is 0 for all access point.
Do you see this phenomenon? Or, does someone see this?
Best,
Takashi
